I ask because those roses and their close cousins are the whole basis of my wedding. I wanted to use roses Jim had given me while we dated... he gives fancy roses (lavender, tiger stripped, etc) I settled on the ones that were yellow that turned into red. The original ones were more like yellow to dusty orange.
I picked the rose THEN planned my wedding. Finally agreed to bright yellow to dark red to go with the Aisan theme we settled on. I got tons of pics of those roses though.
